It’s been a long time, but guess who’s back? Yep – northern lights. As of 9 o’clock (CST) two low arcs of pale green light span the lower half of the northern sky. Not a big deal but easily visible from a dark site even with the moon still shining.
Auroras weren’t in the space weather forecast and the most recent satellite maps depicting the auroral oval show them visible much farther north – Minnesota not included. Of course it doesn’t matter what the instruments say tonight. The lights are out and worth keeping an eye on. Hopefully the solar wind will fan them into a brighter, more intense display.
Right now you’ll need a dark sky with a good northern horizon and a heavy coat to see this small show. Current temperatures across northern Minnesota are all below zero. My thermometer reads -15F. Bundle up!
UPDATE: The aurora blossomed around 10:30-11 p.m. with some bright rays and dappled arcs. Quieter again by midnight.
